Early childhood educators are expected to provide the children in their centers high-quality care and preparation for later school success. At the same time, nearly a third of children enter early care and education settings displaying challenging behaviors, which in turn impacts educators' stress levels and wellbeing. It is then unsurprising that classroom management and providing behavioral supports are consistently identified as areas where educators require further training upon entering the workforce. The purpose of this study is to conduct a systematic review of the empirical literature on professional development (PD) approaches targeting these areas for early childhood professionals. Forty-two studies were identified as meeting inclusion criteria and were coded for strategies targeted, the context and characteristics of the PD series, and the research design and outcomes utilized. Findings revealed that studies were highly variable in terms of targeted strategies, format of administration, training dose, research design, educator and child samples, and reporting practices. The majority of studies were conducted with educators from Head Start and public preschools and utilized research staff in the administration of the PD approaches. This indicates a need for more high-quality empirical evidence on PD approaches that cater to the larger early childhood workforce and centers' needs. Implications for researchers and early childhood mental health professionals and administrators are discussed.
